BASH: How to determine the NIC in the routing table that is tied to the line in the routing table that has 2 instances of 0.0.0.0

I'd like to determine in my bash script which NIC the default gateway is on in order to determine if i need to add static routes via the script or not. Since there are two instances of 0.0.0.0 in the routing table where the default gateway is I'n trying to determine the NIC mentioned in the routing table where there are two instances of 0.0.0.0. Then if it matches ${DftNic} below I no I won't have to add static routes on the server. Scratching my head on this so any help would terrific.

DftNic=$(ip route show | grep default  awk '{print $7}')

is one way
$(ip route show | grep default | awk '{print $5}' )

Open in new window


This is another
netstat -rn | grep ^0.0.0.0 | awk -F' ' '{print $8}'

Open in new window


or just:
netstat -rn | grep ^0.0.0.0

Open in new window
